A TRANSPORTABLE LASER INTERFEROMETRY ABSOLUTE GRAVIMETER TYPE NIM-Ⅱ

GUO YOU-GUANG HUANG DA-LUN FENG YONG-YUAN ZHANG GUANG-TUAN ZHOU, JING-HUA XU JIN-YIN(National Institute of Metrology, Beijing)  
A model of the second generation Transportable laser interferometry absolute gravimeter has been developed in 1985 in China. This apparatus employs the simple free fall of a cube-corner prism. "g" is calculated in accordance with "multiple station" method. This paper describes the optical system for determining falling distance of the dropped object, the precies high-speed electronic counting system and an automatic data processing system. In order to reduce the effect of background disturbances we have developed a new method of data processing. We participated with the gravimeter NIM-Ⅱ in the Second International Absolute Gra-vimeter Comparsion at Severs At in 1985. The result of an international intercomparison of this absolute gaviments shows good agreement with the other instruments. After the second international intercomparison the gravimeter NIM-Ⅱ has been improved. The accuracy achieved is 1×10-7m/s2.
